Avoid defining SIGTTIN/SIGTTOU on Windows.
Setting them to SIG_IGN seems unlikely to have any beneficial effecton that platform, and given the signal numbering collision with SIGABRT,it could easily have bad effects.Given the lack of field complaints that can be traced to this, I don'tpresently feel a need to back-patch.Discussion:https://postgr.es/m/5627.1542477392@sss.pgh.pa.us
